FGF9 and endometrial carcinoma: To investigate the association of Sox7 expression with Wnt/β-catenin signaling activity in endometrial carcinoma, two common Wnt/β-catenin specific targets in endometrioid type cancers; Fibroblast growth factor 9 (FGF9) and Stratifin (SFN) [22, 23] were selected for Q-PCR analysis.
